IIVIPROVEMENI IN CAR-COUPLINGS.

Specification forming part of Letters Patent N o. 193,262, dated J uly17, 1877; application led March 24, 1877.

To all whom it may concern.-

Be it known that I, GEORGE W. MATHEWS, of Ickesburg, in the county ofPerry and State of Pennsylvania, have invented a new and valuableImprovement in Car-Couplings; and I do hereby declare that the followingis a' full,

clear, and exact description ofthe construcside view of my car-couplerattached, and Fig.

5 is a iront view thereof.

This invention relates to devices for coupling cars automatically; andit consists in the construction, arrangement, and combination of theparts hereinafter set forth.

In the accompanying drawings, A A' designate, respectively, two ordinaryrailway-cars, each one of which is provided with a pair of spring-hooksor springjaws, B B, and a drawbar, C, that slides between them. Theouter end of 4said draw-bar is provided with an arrowhead, D, and itsinner end with a block, D', and the rear ends of spring-hooks B areconnected to a slotted block, E, that serves as a guide for draw-bar C.

F designates a downwardly-inclined daring guide-plate suspended fromsaid car below and in front of said spring-jaws B, and serving to directthe arrow-head D o f the opposite draw-bar between said hooks in the act.a coupling.

of coupling. The draw-bar C of either car may be withdrawn under thelatter, so as to offer no impediment to the entrance of the arrow-head Dof the other car; but one of' said arrow-heads must protrude in order toeffect Spring hooks or jaws B B may be opened at will by means of twotransverse sliding racks, E' E', which are connected, respectively, toeach of the said hooks or jaws, or adapted to engage with lugs on them,and operated in opposite directions by means of a pinion, F',

which turns between them and engages there-- with. This pinion is on ashaft, G, and may be operated from the platform of the car by ahand-wheel, H, or from the side ofthe car by a sliding bar, I, which isattached to a horizontal arm, J, of said shaft G. Each draw-bar C isprovided with a retracting-spring, K, inserted between the block D' ofthe draw-bar and the slotted block E.

What I claim as new, and desire to secure by Letters Patent, is-

The combination, with the springjaws B, slotted block E, guide F, racksE' E', pinion F', and shaft G, having the wheel H. of the draw-bar C,having the arrow-head D, block D', and retracting-spring K,substantially as described, and for the purpose set forth.I

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
